The Growler Saver is a Patent-Pending cap and sealer that will keep beer fresh and draft-ready, even after breaking the growler’s original seal. Often if the beer in growlers wasn’t consumed quickly, the beer could not retain its original freshness and carbonation levels. The Growler Saver will ensure that the growler can be opened repeatedly so that the last glass of beer is as good as the first. Available at Merchtex
